There are a few different interview styles:
- Totally competent: Interview led by one or more people that really
know their stuff (no question this is amazon.com the most intensive
quality interview on the planet). Expect questions where you wish you'd
memorized every word Tom Kyte and Jonathan Lewis ever wrote or spoke.
- Aggressive: This is the interview in which one person is insecure
that someone more competent may join the team and either dilute their
influence or demonstrate that their skills are substandard. Expect to
be asked obscure meaningless questions that are irrelevant to the real
work environment.
- Fixed: This interview is often conducted by someone that hasn't a
clue in the world what they are doing but got a list of questions and
answers. Or may be conducted by a government-related agency where they
are required by some twisted concept of fairness to ask the same
questions of each person interviewed. The secret is to know the answers
written on the paper ... even if they are obsolete or incorrect. This
interview is something like taking the 9i OCP.
- Honest: Jack Cline, Chair of PSOUG once sat in an interview with a
very large bank in which the interviewer said: "If I knew what questions
to ask you I wouldn't need you." He got the job and they were lucky.
No doubt others can add to this list.
But my point here is that just because some self-annointed expert is
asking questions doesn't mean that they have a clue what they are
talking about.
About a year ago I sat in on a 10g interview where a member of the
internal team started asking questions about logging on as internal:
He was still working in 8i.
